This invention relates to improvements in glare shields and may beconsidered as an improvement over the construction disclosedin mypending application Serial No. 567,879,

filed October 9, 1931.

An objectof the present invention is to provide a glare shield having atrack and a shield with an improved construction for fastening 1 ormounting the shield on the track, enabling w the shield to be eitheradjusted along the length of the track or to be swung about the track toswing it into an upper position where it is inoperative, or to be swungabout avertical axis, so that the'same shield may eifectively shield thedriver of an automobile from light rays reaching him from the side.

More specifically an object of the invention is to provide an improvedconstruction for q mounting the shield on the track which is ofextremely simple design facilitating manufacture and assembly and whichwill effectively hold the'shield in any of its adjusted positions, atthesame time facilitating easy adjustment. 7 I

'lNith the foregoing and other objects in view, which will be mademanifest in the following detailed description, and specifical- 1ypointed out in the appended claims, referenceis had to theaccompanyingdrawing for an illustrative embodiment of the invention, wherein: 1

Referring to the accompanying drawing,

wherein similar reference characters designate similar parts throughout,the track on which the glare shield is mounted is indi- Gated at 10,this being a metallic bar preferably of rectangular cross section and ofsuitable length.

The centers of the parts of the'clamp are bowed outwardly to form acylindrical opening therebetween which receives pin 14. In the pin thereare formed a pair of apertures for the reception of a small stop 'pin18. This stop pin is receivable ineither of the apertures 19 and extendsthrough a slot 20 formed in theclamp 15. The purpose ofthis constructionis to enable the glare shield 17 to be turned about a vertical axis fromthe position shown in Figures 1 and 2'between limits, these limits beingestablished by the engagement of the stop pin 18 with the ends of theslot 20. The bolts or rivets 16 firmly hold parts of the clamp 15 inengagement with the oppositesides of pin 14 so that although the glareshield may be turned, it is frictionally held in any adjustedposition.

WVithin the housing 13 there'is a sectional bushing, one sectionbeing'indicated by the reference character 21 andthe other sectionbeingindicated at 22. These sectionsfeach fpresent'. on their exteriorsapproximately semi-cylindrical surfaces complementary to the cylindricalsurface on the interior of bushing 13. On the section 21 there is formeda longitudinal groove 23 in which the track 10 is disposed. In theopposite section "22 there is likewise formed a longitudinal grooveindicated at 24 the bottom of which is preferably curved as indicatedinFigure-4 to (m stitute a seatfor anarcuate spring 25. The

7 At the ends of the bar there are brackets 11 and 12 by whichit may be'mounted on the interior of a vehicle such engaging face of section 21is recessed back track and to form seatstor the ends of spring 25. Theseshoes carry integral handles and 33. The engaging face of section 22 ofthe sectional bushing has its ends beveled oil as indicated at 34 and35, this beveling serving to accommodate a slight movement of the shoes28 and 29 when the handles 32and 33 are moved toward each other. In theposition shown in Figure 4 the spring 25 urgesthe shoes 28 and 29 intoengagement with track 10 and as the shoes bear upon section 21' of thesectional bushing the spring also serves to become eii ective throughthe shoes to spread the sections of the bushing within the housing,urging the sections into engagement with the interior of the housing.This engagement between the shoes and the track serves to hold the housing in any adjusted position along thelength ot the track. However, itis possible to disengage the shoes from the track to enable adjustmentof the glare shield and associated structure along the length of thetrack. 7 This is accomplished by moving the handles 32 and 33 towardeach other, the shoes'tulcruming at their inner ends on section 21against the action of the spring 25. In this way the effectiveness ofthe spring is counteracted so that there is no part of the structurepressing on track 10' to hold the construction in any adjusted positionand the entire structure ma be caused to slide alon the track I thetrack passing freely through groove 23.

On release of the handles the spring returns the shoes into engagementwith the track to hold the shield in adjusted position. The expansion ofthe sections of the bushing with in the housing causes the housing to befrictiona'lly held in any adjusted position. The sections of the bushingare, maintained in aligned position within the housing by, means of akey 36 of L shaped form, as shown in Figure 3. This key is receivable inaligned slots 37 and 38 formed in the opposed faces of the sections 21and 22 of the sectional bushing. The small lateral end 39 extendslaterally beneath the track so that the key is ettectively locked inplace "by the track so that it cannot be removed out of the slots 37 and38. The outer end of thekey extends through the key and the movement ofthe housing on the bushing is guided by the key moving in slot 40.

In Figures 8, 9 and 10, there is illustrated an alternative form ofconstruction wherein the housing is indlcated atf1-5, having a slot {l6circumterentially thereon. Within this the sections 21 in groove 24:.

housing there is a sectional bushing, the parts of which are generallydesignated at 17 and 4:8. Referring specifically to Figure 9, the partor the sectional bushing indicated at l8 presents a cylindrical outersurface fitting the interiorof the bushing. It is longitudinally groovedwit a relatively deep groove 49 and at its ends it has notches 50 and 51for the reception of the shoes which engage the track. These notch-cs orrecesses have outwardly diverging sides so that they are somewhat Vshaped'in form to accommodate the slight movement of the shoes necessaryto disengage the shoes from the track when the shoes pivot about theirinner ends which are disposed in the inner ends of notches 50 and 51.The shoes employed in this type ofconstruct-ion areidentical with shoes28 and 29, having the bends at 30 and'31 and the integral handles 32 and3; At about its center it has a transverse slot 52. The opposite side ofthe bush: orthe other sectional part is shown in this part beingindicated at 48, and it is equal in length the length of part Its widthis such that-it fits snugly in the groove 49. It has a transverse slot53 adapted to be caused to'register withslot 52. A key is provided whichis receivable through slots and 53. It has a laterally extending portion55 which is receivable in a notch formed in a side edge of'spring 56.This key also has a linger 57 disposed in. l The track in this form isindicated at 58 and is disposed against one side ot 'groove .49. Thespring hti'which urges the shoes into engagement with the track, similarto spring 25, is disposed in the" groove and urges section 48 outwardlyagaiiist the housingand by reaction the opposite section of the bushingis urged into engagement with the housing and the shoes are urged intoengagement with the track. The key withits finger 5'? in groove 46guides the rotational movement of groove 46..

the housing with respect to the. bushing. It 7 is held in pla'ce by thespring 56 which forces the key to the bottom trslot 53. The key cannotbe easily withdrawn because of the laterally extending portion 55hearing in the sections ot'the sectional bushingycan be easily actured.I In assembling and quickly inanuf a d 22 of the bushing are broughttogether and the spring 25 positioned 38 are caused to align with slot40. The key 36 then inserted and the track 10 is slid into groove 23 tolock the key in fplace. The shoes 28 and 29 can then be caused to slideinto the recessed ends of section '21 and when their groovedportions30a1id 31 encounter the ends of the springs 25 the ends willsnap sections of the bushing are then inserted in the housing and. slots37 and a on pin 14.

in place and thus fasten the shoes against to frictionally engage thehousing. The purv pose of having the stop pin 18 receivable in eitherofthe apertures 19 is to enable the glare shield to be reversed withrespect to the housing so that the device can be used either for rightor left hand drive automobiles. Whenever it is desired to swing theglare shield about a vertical axis from the position shown in Figure 2to cut off lateral rays, the glare shield may be merely grasped andturned, in which case the clamp merely turns When it is desired to swingthe glare shield into an uppermost or horizontal position, it maylikewise be merely grasped and turned, in which case the housing 13turns on the sections of the bushing. When it is desired to adjust theglare shield laterally, the

' handles 32 and 33 are merely pinched toward each other, disengagingthe shoes from the track, thusenabling easy quick adjustment of theglare shield in all positions.

Various changes may be made in the dc tails of construction withoutdeparting from the spirit or scope of the invention as defined by theappended claims.
